Özet

This study determined the association between Myf5, CAST and MSTN genes and fattening

performance traits in 228 (Holstein ¼ 103 and Brown ¼ 125) cattle breeds. Classification

and regression tree (CART) was used to determine association between genes and fattening

performance. The allele frequencies of Holstein cattle in terms of Myf5, CAST and MSTN

genes were A:0.30, B:0.70; A:0.43, G:0.56; A:0.97, B:0.03, respectively, whereas in the Brown

Swiss cattle were A:0.36, B:0.64; A:0.65, G:0.34; A:0.88, B:0.12 respectively. The Myf5, CAST,

and MSTN genes were found to be in the Hardy–Weinberg equilibrium (p > 0.05) in both of

the cattle breeds. As a result, the association between Myf5, CAST and MSTN genes and fattening performance traits were found to be significant according to CART analysis.
